IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 155,079, dated September 15, 1874; application filed August 15, 1874.

To all whom it may concern: Be it known that I, JOSEPH GOODMAN, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Brick-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to certain improvements in machines for makin g perforated brick and it consists of a mold notunlike in shape to a hollow truncated pyramid in a horizontal position, and being provided with a series of vertical bars, to which are attached a suitable number of round rods; also, an endless apron of leather or other elastic material, in combination with the several parts of a brick-machine, as will hereinafter be fully shown and described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification, Figure 1 is a top view or plan of my improvement in brick-machines. Figs. 2 and 3 are side elevations of the same. Fig. 4 is a front-end elevation of my improve ment. Fig. 5 is a vertical and longitudinal section of the same.

In the drawings, A represents the base of the machine, upon which are secured the housings B, in which are supported the rolls G and D. On the axis of the roll D is a large gearwheel, 9, into which meshes the pinion-wheel e on the end of the driving-shaftf. On the opposite end of the axis of the roll D is a wheel, 6, which gears into a wheel, h, on the axis of the roll O. To the front sides of the housing B is secured the mold J, at or near the inner edge of which are a series of vertical bars, 70. From these bars project horizontally a series of round bars, 1, which form the apertures in the formed clay passing from the mold upon the endless apron m. The walls of the mold J are tapering, or converging from their inner edge to their outer edge. The endless apron m should be constructed of leather or other strong elastic material. n represents a frame pivoted at 0. This frame is provided with a series of fine wires, 11, which frame with its wires is used for cutting the clay into suitable widths for forming the brick. r represents the feeding-bench, upon which is placed the clay which has been previously tempered.

The operation of my invention is as follows: Motion being imparted to the rolls, tempered clay is placed upon the feed-bench r, and fed forward to the rolls, which carry it forward into the mold J, from which it is forced out upon the endless apron m by the incoming clay fed forward by the rolls. At suitable intervals the operator draws down the frame a, and cuts the formed clay into suitable widths for brick, which are then carried forward on the endless apron, and delivered on hearingoif boards, and then dried and burned in the ordinary manner.

I disclaim the peculiar shape and general construction of the mold with an inner lining of glass, as also the bearings of the horizontal round bars, as is shown in patent to P. N. Woliston, of August 11, 1868, and numbered 80,890. I also disclaim the construction and use of the endless apron or cutting-platform, consisting of a series of rollers arranged side by side, as shown in patent to Thomas Dixcee, of May 7 1867, and numbered 64,504.; as also the patent to F. Beaujeu, of December 26, 1871, and numbered 122,214; but

What I do claim as new, and desire to secure by Letters Patent, is

The combination of the rollers O D, mold J, provided with vertical bars k, to which are attached horizontal rods 1, to form perforations in the clay as it issues from the mold, feedbench r, cutting-frame n, to operate as and for the purpose set forth.

In testimony I hereunto set my hand this 21st day of March, A. D. 1874:.

JOSEPH GOODMAN.
